WALTER P. MURPHY, or 's'r. LOUIS, mssomu.

can-noon.

To all whom it may concern:

Be it known that-I, W'AI/rnu P. MQRPHY, a citizen of the United States,residing at St. Louis, State of Missouri, have invented that willwithstand the weights usually im-' posed on such roofs and at the sametime adapt itself to the usual strains incident to the travel of a carwithout tearing the sheets-or their fastenings, and with'this and minorobjects in view my invention consists of the parts and combination ofparts as will be more-fully hereinafter set forth.

In the drawings Figure 1 is a transverse. section of a car brokenaway,with my roof applied. Fig. 2 is a top plan view of the same, the roofingsheets being partially broken away. Fig. 3 is a section on the line 3-3,Fig. 2. Fig. 4 is a section on the line 44=.Fig. 2 the carline beingshown in elevation. Fig. 5 is an enlarged sectional view on the line 66Fig.2, showing oneof the small eaveclips in elevation Fig. 6 is an enlared perspective view of the end of the carIine.

In the drawings Ihave illustrated my invention as applied to a carhaving wooden side sheathing 15 and side plate 16, but it is evidentthat my improvements may be applied to all metal cars. The purlins 17are shown as constructed of wood in Figs. 1 and 2, but for all metalcars and for extra lare wooden cars, I prefer to construct the pur in ofmetal to materially strengthen the cars and raise them against endthrusts.

The purlins are notched as at 18 to receive the carlines' 19, the foot20 of the carlines-being seated in said notch as shown in Fig. 3. Theobject of setting'the carlines in a notch in the purlins is that I amenabled to use a very heavy T iron to get a strong oarline withouthaving too much-I 012a projection on top of the roof, thus enabling meto make a low seam between the sides of the roofing sheets and obviatingthe danger of trainmen tripping on the same. If seams are very'high on.a roof, a trainman is apt to trip over them and be thrown from ,t e roofof the car. l

The carline is formed on the arc of a circle thus forming a circularroof and enabling me.to use a solid roofing sheet ex- Specification oflLetters Patent. Patented J une 25, 1912, Application filed January 13,1910. Serial No. 537,950.

tending from one side of the car to the other, thus eliminating theridge seam. The web of the carline is cut down on a curve toward its endas at 21 to provide clearance at the eaves of the car for tunnelbridges, etc., and at the same time furth r reduce the height of theseam between the roofing sheets at the eaves, thus reducing the area oftheopening through which the elements may enter. The roofing sheets 22are bentupward at their side edges as at 23 a distance equal totheheight of the carline above the purlin and fit snugly against thesides of the carline as shown in Fig. 3. A metal cap 24 is fitted overthe car-line and theends 23 of the roofing sheets; the lower edges ofthe cap being bent out to adapt them to fit snugly on the roofing sheetsas shown in Fig. 3. If found necessary, the space between the roofingsheets and the top of the foot 20 of the carline, in the notch 18, maybe filled with a suitable filler.

The purlins are suspended from the carlines by suitable bolts 25. 'Ithas. been found that the-nuts on these bolts frequently work off andthus the purlins are liable to drop in the car and not only weaken thestructure but damage the load. To obviate this, I secure, by riveting,clips 26 to the car"- lines and pass themunder the purlins', the openend of the clips extending toward'the center of the car. running board28 is secured by means of bolts 29.

The clips 32 are provided with a hood 33 constructed to cover the end ofthe roof seams against the elements; in order to hold this hood up toprevent its edges dfrom coming in contact with the roofing sheets, Iprovide it with a lug 34 which is constructed to rest on the base of thecarline between the upturned side edges 23 of the adjacent roof sheets,thus constituting a firm ,su port for the hood. In order to furthersuiiport the clips 32, a hole is formed in the car ine,

near its outer end and one end of a bolt 32" cured by means of t e nut32". This holds The saddle 27 for the.

the top of the clip firmly against outward movement, thus the clip holdsthe roofing sheets more firmly against cn'dwise movement. In thisconstruction it IS not necessary to make any holes in the top of' the.the side plate 16.

web of the carline and extending through the face of the clip'to whichit is secured by means of the nut 32. This clip is poz'sitioned, at theend of a roof seam, and in view of the fact that the base of the metalcarline is bent down on the side of the car or fascia, the-use of theusual clip would necessitate drilling bolt holes in the end of thecarlin'e to fasten the "clip. In order to obviate this, I provide theclip with an apron 35 of considerable area with bolt openings to receivebolts 37 which are secured to the side plate 16. Extending below theapron is a lug 39 fitting snugly against the side of the car or fascia.This lug with the apron 35, constitutes a lever to resist the tendencyof the roofing sheets slipping endwise.

If found desirable or necessary, the end 40'of the carline may beprovided with a bolt opening, whereby it may be secured to The roofingsheets are bent over the eaves down onto the fascia and are providedwith openings 41 in which thiinbles. or spacing members 42 arepositioned. The nail, bolt or other fastening means 43 passes throughthe thimbles into the fascia to secure the ends of the sheets at theeaves. The bolt 43 is of less diameter than the'opening in the thimble,thereby providing for movement of the sheet without placing any stresson the bolt 43 or the sheet, whereby the sheets may adapt themselves tothe usual twisting and weaving of the car in transit without looseningthe fastening at theeaves.

What I claim is 1. A car roof including a metal carline of invertedT-shap e' with its web terminating short of its ends forming notches,movable roof sheets having upturned flanges arranged on each side ofsaid carline, a seam cover positioned over said web and roof sheetflanges and flexibly engaging the latter to retain the roof sheets inposition, and a roof clip covering the end of the carline and seam capat the eaves of the car and having a fastening means securedto the webof the carline in longitudinal alinement therewith. 2. A car roofincluding a metal carline of inverted 'T-shape witlrits web terminatingshort of its ends forming notches, movable vroof sheets having upturnedflanges arranged. on each side ofsaid carline, a seam cover positionedover said web and roof sheet flanges and flexibly engaging the latter toretain the roof sheets in position, and a'roof clip covering the end ofthe carline and seam cap at the eaves of the car and having a projectionextending into the notch .left atthe-end of the web, and having a fas- 7teningsmeans secured to the web of the car- ..llne in longitudinalalinement therewith.

' Copies of this patent may be obtained for .3. In a car roof, sheetshaving downturned end flanges overhanging the eaves, openings in saidflanges, root clips spaced from said sheets, said clips having spacingprojections on their inner sides bearing against the car body above andbelow the lower edge of said sheet flanges. and means passing throughsaid clips andsaid openings for securing said clips to the car body.

4. In a car roof, sheets having downturncd end flanges overhanging theeaves, openings in said flanges. roof clips, a spacing member at thelower end of said roof clips bearing upon the car body below the loweredge of the said flanges, and a spacing memberintermediate the ends ofsaid clips projecting through the openings in the downturned end flangesof the sheets and bearing on the car'body, and means passing throughsaid clips and said openings for securing the clips to the car body.

A car roof comprising carlines having a web and laterally extending baseflanges, the base flanges extending beyond the ends of the web and bentdown and secured to the side plate of the car. roof sheets havingupturned side edges which are disposed alongside of the carline, a capextending from eavesto eaves of the car and covering the carline andupturned edges of the roof sheets, a seam clip having a hood housing theend of the seam, a tongue projecting within the hood to engage thecarline, and an apron depending from said hood below the eaves of thecar, a fastening passing through the apron and the side of the car tosecure the clip to the car below theeaves, and a fastening securing thehood to the carline above the eaves to prevent the hood fromtilting.

6. A clip for a car roof havinga hood closed at one end and an aprondependin from said hood, the closed end of the hood having a boltopening extending in the direction of the longitudinal axis of the hood,said apron being provided with a bolt opening near its lower end,whereby the clip may be anchored above and below the eaves of a car.

7. A car roof including a carline, and a clip having a hood, an aprondepending from the hood, and a tongue arranged within the hood to engagethe carline,- and a main fastening securing the apron to the side of'thecar below the caves, and a sec-- WALTER P.
